WELT COATING MACHINE Filed Nov. lO, 1,952 2 Sheets-Sheet 2 Patented Sept. 24, 1935 UNITED STATES NT @HQE WELT COATING MACHINE New Jersey Application November 10, 1932, Serial No. 642,072, In Great Britain December 1, 1931 26 Claims.

This invention relates to machines for preparing welting strips for use in the manufacture of welt shoes and more particularly to a machine for coating that portion of a strip of welting which is to receive the inseam stitching, which unites the welting to the shoe upper and insole, with a sealing substance which will aid in waterproofing the shoe along the inseam and at the region adjacent to the inseam. It is to be understood, however, that in many of its novel aspects the invention is not limited merely to treating welting strips for use in producing shoes with sealed inseams, but may be used for coating various other articles and materials such, for example, as fabrics or rubber.

In the Imanufacture of certain types of Welt shoes the welting strip is prepared by beveling its inner edge and by grooving its flesh surface and sometimes also its grain surface, adjacent to the beveled edge, to receive the row of stitching which is to unite the welting to the shoe upper and insole. When the welt is attached toy the shoe, this line of stitching or inseam passes through the stitch-anchoring groove in the flesh side of the welt and through the groove in its grain surface, which lies next to the upper, if that surface is grooved, thus permanently securing the welt to the upper and insole. In order to insure that the shoe will be water-tight along the inseam after the welt is attached, it has been proposed in United States Letters Patent No. 1,937,826, granted December 5, 1933, on an application led in the name of R. A. Linehan for improvements in the Manufacture of shoes, to coat the welting strip with a sealing substance which will ll the groove formed on the side of the welt which lies next to the upper and will cover a portion of the welt adjacent to this groove, thereby sealing the inseam stitches and aiding in rendering the shoe waterproof.

It is an object of the present invention to provide an improved machine whereby the coating of welting strips with a, sealing substance can be effected rapidly, accurately, and with facility. To the attainment of this object and in accordance with a feature of the invention, the illustrated machine is provided with novel means for applying a coating substance to a welting strip, said means comprising a rotary applying member which is arranged to deposit the coating substance downwardly on the welting strip as the strip is fed transversely of the periphery of the rotary applying member from side to side thereof. In the construction shown the rotary "I member is mounted on a, horizontal axis located substantially parallel to the path of feeding movementl of the welting strip and the strip is fed lengthwise across the applying surface of the rotary member, scraping the coating` substance from the latter and depositing it on a 5 marginal portion of the welting strip during the feeding movement.

Another feature of the invention resides in novel means for supporting the welting strip with one of its sides in contact with the periphery y of the rotary member during the rotation thereof, and for holding this side of the strip in contact with the periphery of the rotary member during the feeding movement. Preferably, and

as illustrated, this is accomplished by means of a thrust member which presses the strip toward the firm-surfaced periphery of the rotary applying member, the thrust member being slidably mounted in a guideway formed in the frame of the machine and having a tongue for supporting 2d the portion of the strip in contact with the rotary member against the downward thrust of said rotary member. Means is provided in the illustrated machine for urging the thrust member inwardly toward the rotary member, thus keeping the welting strip in proper contacting relation to the periphery of the rotary member as the strip is fed through the machine.

Other features of the invention reside in novel means for limiting the area of the surface of the welting strip which is to be coated, and means for controlling the quantity of coating material deposited on the strip. As illustrated, the limiting means comprises a gage member which bears against a portion of the length of the welting strip during its feeding movement and acts as a fence to limit the area widthwise of the strip which receives the coating substance. The means for controlling the quantity of coating material applied to the welting strip comprises a, controlling gage in the form of a block, located in the path of feeding movement of the welting strip between the rotary member and the feeding means, and arranged to bear lightly against a portion of the upper surface of the welting strip as it is fed through the machine to scrape off or hold back the surplus. The controlling gage or block may, if desired, be provided with a groove to permit the passage of a bead of coating substance which extends above the surface of the welt.

The invention also includes as further features novel means for adjusting the controlling gage and for withdrawing it from engagement with the welting strip, and means for retracting the width gage and the thrust member simultaneously in order to permit the introduction of a welting strip to the operating instrumentalities. In the construction shown, the means for withdrawing the gages consists of manually operable members which are so located that an operator may operate and control them with one hand thus leaving the other hand free to insert a welting strip into the machine.

The above and other features of the invention, including certain details of construction and combinations of parts, will now be more particularly described by reference `to the accompanying drawings and thereafter pointed out in the claims.

In the drawings,

Fig. 1 is a front elevation partly in section of the upper portion of the machine in which the present invention is embodied;

Fig. 2 is a plan View of the machine shown in Fig. 1 with the top cover removed;

Fig. 3 is an elevation of the welt strip feeding mechanism as viewed from the rear in Figfl;

Fig. 4 is a vertical section through the feed rolls; and

Fig. 5 is a cross section on enlarged scale of a strip of welting after the coating substance has been applied.

The illustrated machine comprises a base I2 the upper portion of which forms a reservoir I4 which contains the coating substance that is to be applied to the welting strip. A coating substance or wax which may advantageously be used for coating strips of welting or other articles of this nature is disclosed in the above-mentioned application and contains asphalt, Chattertons compound and resin. The` invention is not limited to the use of such substance, however, but is intended to include any substance of this general nature which can be applied to strips of welting or similar materials for the purposes herein set forth. The under side of the reservoir I4 may beheated in order to melt the coating substance and keep it in liquid form until it is applied tothe welt. Heat may be applied to the reservoir by any suitable means-such, for example, as a gas burner illustrated at I6 or an electric heating unit (not shown) which may be introduced in a recess I8 formed under the reservoir Afor this purpose. The top of the reservoir is provided with a removable lid or cover I1 which retains .theheat in the reservoir.

,The coating substance is applied to thewelting stripfrom the periphery of a'rm-surfaced rotary applying roll 20 and is supplied to the applying roll by means of a supply roll 22, the lower portion of which dips into the coating substance contained inthe bottom vof the reservoir. The supplyroll 2,2-is rotatably mounted on the lower arm of a bell crank lever 24, pivoted on a stud 26 mounted in ears formed in the lower portion vof the reservoir. The other arm of the bell crank lever 24 extends upwardly and is threaded at its upper end to receive a screw 25 which passes outside the reservoir through an opening and has mounted on its outer portion a spring 27. The inner end of the spring 21 bears against a washer mounted on the screw 25 and bearing against the outer wall of the reservoir and the other end of the spring presses against an enlarged head 28 of the screw and tends norma-llyto force the screw outwardly, thus causing the supply roll :'22 to: beurged upwardly into peripheral engagement With the applying roll 20.

The-applying roll 28 is `secured to a horizontal shaft 32 rotatably mounted in'bearings formed on the side walls of the reservoir. The shaft 32 is rotated through spiral gears 34, 36 by a driving shaft 38 journaled in bearings formed outside the reservoir and extending laterally of the machine and at right angles to the shaft 32. shaft 38 has a handle 40 by which it may be rotated when the machine is in operation. The applying roll 20 is rotated in a clockwise direction, as viewed in Fig. 1, so that the coating substance deposited on its periphery by the supply 10 roll 22 will be carried over the top of the roll and deposited downwardly or piled upon a marginal portion of the upper or grain surface of a welt strip 44 (Fig. 1) as the latter is being fed across the periphery of the roll in a manner hereinafter 15 to be described.

The thickness of the film of coating substance on the applying roll 20 may be controlled by a scraper plate 90 adjustably secured to a lug formed inside the reservoir. The scraper plate 20 90 may be provided with grooves 92 (Fig. 2) for controlling the amount of coating substance carried by the applying roll and, if desired, the peripheries of the supply roll and applying roll may also be provided with grooves (not shown) in or- 25 der to increase the quantities of coating material carried by the rolls.

Progressive feeding of the welting strip is effected by a pair of cooperating feed members comprising a feed wheel 42 and a presser roll 46. 30 The feed wheel 42 is mounted on the drive shaft 38 and is substantially equal in width to the widest welting material which is to be coated. The periphery of the feed wheel is obliquely grooved or ribbed (Fig. 3)` so that the welting 35 strip 44 will be held from slipping as it is fed over thetop of the wheel. The grooves are so inclined that the welting strip will be urged laterally toward the applying roll as it passes over the periphery of the feed wheel. The presser 40 roll 46 is rotatably mounted in a forked carrier 48, directly above the feed wheel 42, and is adapted to press the welting strip 44 firmly against the feed wheel during the welt feeding operation. provided with horizontal grooves which cooperate with the oblique grooves in the feed wheel 42 to prevent the welting from slipping as it is fed through the machine. The carrier 48 for the presser roll 46 is mounted in a bracket 50 xed 50 to the reservoir I4 and a spring 52 (Fig. 3) tends normally to force the presser roll downwardly into engagement with the feed wheel. 'Ihe presser roll 46 is considerably narrower than the feed wheel 42 and is so located with respect to the feed 55` Wheel that it will press upon a portion of the welting strip which is not to be coated. Since the axes of the feed wheel 42 and the applying roll 20 are at right angles to each other, the welting strip 44 is fed laterally across the pe- 60 riphery of the applying roll in a path which is parallel to the axis of said applying roll and perpendicular to the axis of the feed wheel. The presser roll 46 may be separated from the feed wheel 42, to permit a welting strip to be inserted between them and to this end there is provided a lever 54 pivotally mounted at 56 on the bracket 50 and connected by afscrew 51 to the carrier 48. When it is desired to introduce a welting strip into the machine the lever 54 may be rotated about 70 its pivot 56 by means of a small latching hand lever 58 to lift the presser roll 46 and hold it away from the feed wheel, thereby providing space to insert the end of the welting strip between the feed members.

The driving 5 The periphery of the presser roll 46 is 45r When a melted coating substance of the nature referred to is used, it has been found that a satisfactory coating may be applied to a strip of welting by utilizing an applying roll about three-eighths of an inch wide and by feeding the welting past the applying roll `at a speed equal to the peripheral speed of the applying roll. In the construction shown this may be attained by employing a feed wheel ft2 of half the diameter of the applying roll 2G and by arranging the spiral gearing 34, 3S, through which the applying r-oll is rotated, so that the applying roll shaft 32 will be rotated at half the speed of the feed wheel 15?.. A convenient diameter for the applying roll under these circumstances is about two and three-quarter inches.

In order that the welting strip 44 may be supported in the desired relation to the applying roll 2li, as it is fed through the machine, there is provided a device for holding the strip against the periphery of the applying roll with the surface which is to receive the coating substance uppermost. This device comprises a thrust member 62 (Fig. l) mounted for sliding movement toward and away from the applying member in a horizontal slo-t 63 (Fig. 2) formed in a supporting portion 66 projecting from the side of the reservoir adjacent to the feed rolls 42, 136. The thrust member 62 has a strip supporting tongue d4. This slot is located opposite the periphery of the applying roll 2Q and the upper surface of the tongue (ill is substantially alined horizontally with the top of the feed wheel 42, in a plane substantially parallel to the axis of L the applying roll 2i! and intersecting its periphery. At its inner end the guideway opens into a horizontal guideway having a side surface 63a parallel to that element of the periphery of the r-oll 20 which contacts with the edge of the welting and, as shown, is parallel to the axis of the applying roll. The guideway also has a bottom surface 63h (Fig. 4) in a plane intersecting the surface of the applying roll. 'Ihis guideway 630#J 83h extends transversely of the applying roll and i in it is supported the welting strip as it is fed through the machine. The top of the tongue 64 (Fig. 4) is level with the bottom i535 of the guide- Way and together they support the welting strip. The edge face 44a. (Fig. 5) of the welting strip adjacent to the sewing groove (and to the coating groove 5l if the latter is present) is kept in close Contact with the periphery of the applying roll 2t by the thrust member 62, which is pressed inwardly toward the periphery of the ap- 1 plying roll at right angles to the path of feeding movement of the welting strip by a leaf spring 58. The thrust member S2, adjacent to the tongue 64 (Fig. 1) which supports the welting strip directly in front of the applying roll, has a vertical surface 66, for engaging the edge face Mb of the welt opposite that which contacts with the applying roll, thereby to press the welting strip against the periphery of the applying roll to scrape off the coating substance and to deposit it on the margin of the top or broad face Mic of the welting strip, filling the groove 6l if there is such a groove. This grooved-upper face or grain side of the Welt will be next to the upper and the coating substance will seal the inseam stitch and aid in rendering the shoe Waterproof. The leaf-spring @8, which urges the thrust member 62 toward the periphery of the applying roll, is mounted -on a projection 59 formed at the lower portion of the reservoir.

In order to limit the area widthwise of the welting strip to which coating substance will be applied or can spread, there is provided a width gage l0 comprising a fence-like plate pivoted at l2 to the support B and having a portion of its lower edge bearing against the upper surface -of the welting strip (Figs. 1 and 4). The width gage l0 is positioned parallel to the length of the welting strip as the latter is fed through the machine and is pressed downwardly by means of a leaf-spring i4 (Fig. 2) secured to an upper portion of the support Si) and bearing against the top edge of the gage plate. The gage 'iii is thus caused to press against a length of the welting strip for a predetermined distance either side of the location where the welting strip passes the periphery of the applying roll 20.

The thickness of the coating applied to the welting strip is determined by a controlling gage in the form of a block "16 pinned on the inner end of a horizontal rod 'l pivotally mounted in the supporting portion @il of the reservoir. The block or gage 'F6 extends over that portion of the welting strip which has been coated and acts to scrape excessive material from the surface, thereby controlling the thickness of the layer of coating substance applied to this surface. The controlling gage is located (as shown in Fig. 2) at a point in the path of feeding movement of the welting strip that is behind the applying roll 2@ and in front of the feed Wheel and presser roll. The gage is spring pressed about its pivot 7S so that it will bear downwardly upon the upper surface of the welting strip as the latter is fed through the machine. The under side of the controlling gage 1S may be grooved as at l? (Fig. (i), when so desired, to permit the passage of a bead 'i9 of coating substance which extends above the surface of the welting as shown in Fig. 5 directly over the filled groove 6l.

The gages lil, l@ are each provided with manually operable means by which they may be lifted when a welting strip is being introduced into the machine, such as a knob E@ secured to the forward end of the gage It, and a forwardly extending lever 82 the rear end of which is secured to the rod 'i8 which forms the pivot for the controlling gage lli. The lever 82 may be swung upwardly by an operator to rotate the rod le and lift the gage l@ away from 'the welting. downward movement of the lever to position the gage and control the thickness of the coating substance, being limited by an adjustable screw threaded through an overturned portion of the lever and arranged to engage the upper surface of the support til. The upper edge of the width gage lf! is beveled at a portion of its length which lies in front of the applying roll ile. A slide plate 8S, adjustably secured to the thrust member 62 and arranged to slide in a groove formed in a cover plate 88 mounted on the support Eil, has its forward edge, which is contiguous to the gage l, beveled so that it is complemental to the bevel on the edge of the width gage. When the width gage is raised to permit a welting strip to be inserted underneath it, these beveled surfaces come into engagement with each other and the thrust member 52 is forced back against the spring 68, thereby creating sufficient space between the applying roll 2i) and the vertical surface et of the thrust member 52 to permit the welting strip to be inserted therebetween,

In the operation of the machine the gages lll, 'l' are first lifted by the manually controlled members SB, t2 and a welting strip lili or other Cil piece of Work is inserted in the guideway 63a, 63h formed in the supporting portion G. The drive shaft 38 is then rotated by the handle G to actuate the feed wheel 42 and, through the gearing 34, 36, to rotate the shaft 32 and the applying roll 20. The supply roll 22, which is rotated by frictional engagement with the applying roll 2S, is caused to pick up coating substance from the reservoir I4 and deposit a layer on the periphery of the applying roll. The applying roll then deposits the coating substance downwardly on the margin of the broad upper surface 44C of the welting strip M, as the latter is fed laterally across its periphery by the feed wheel 42 and presser roll 45. The wel'ting strip is held in proper relation to the periphery of the applying roll by the action of the thrust member GZ, which forces the narrow edge face 44a. of the strip adjacent to the roll in close contact with the periphery of the roll thereby to scrape 01T the melted wax. The under side of the strip directly in front of the applying roll is supported during the feeding movement by the tongue 61! which extends forwardly to within a short distance of the periphery of the roll. The Wldth gage lt limits the area of the coating substance applied widthwise of the welting strip and, as the coated surface of the strip is fed past the controlling gage i6, the acting edge of the gage scrapes oilE the excessive coating material, thereby determining the thickness of the layer of coating substance remaining on the broad upper face Mc of the welting strip.
